摘　　要：为了使电脉冲除冰(electro-impulse de-icing,EIDI)系统中的高压储能电容器组高效、安全地充电,研究了一种基于DSP控制串联谐振型拓扑结构的脉冲电源。通过建立不同工作模态时的等效电路,理论分析并推导了电容器组的平均充电电流,同时通过合理设计脉冲电源的工作频率和谐振元件参数,使其工作在欠谐振状态,从而实现在较宽电压范围内的电容器的恒流充电和零电流软开关工作。因此当除冰用传感器检测到机翼表面有冰层时,即可使脉冲电源工作以达到除冰要求。In order to achieve the high voltage capacitor bank of the electro-impulse de-icing system efficiently and safely charging, a series resonant topology pulse power supply based on DSP is researched in this paper. The average charging current of the capacitor bank is concluded by establishing the equivalent circuit of the different working mode, then the operating frequency and resonant parameters are designed, which ensure power supply work in under resonance state, in order to achieve a wide range of constant current charging and zero current soft switching state. Therefore, when the sensor detects the ice of the wing surface, the pulse power supply will work to de-icing.
